First: CLEAN your AR
Second: CHANGE AMMO - there's a reason that PMC is relatively cheap. It doesn't burn as clean as most of the name-brand stuff.
Third: Try using a Colt mag in your Colt AR. Yeah, I know they're a bit spendy, BUT they should work if nothing else does. (Mag-Pul makes a good mag, but many AR's are kinda testy about what's stuck inside 'em.) If you still have problems when using a Colt mag, you should probably tell Colt the whole story.
An unreliable AR is like NO WEAPON AT ALL - not even very useful as a club.
